  • Figure 6 is a view in elevation of one of the spacer discs for the spools
  • Figure 7 is a perspective view of the tension disc
  • Figure 8 is a view showing the relation between a spool hub and the spool supporting shaft.
  • this invention relates to improvements in the ribbon spool tensioning and locking means shown in the Myers and Handley application filed June 25, 1931,
  • the typewriting machine includes a main frame A on which a carriage B is supportedfor letter space movements.
  • Type bars F cooperate with the platen, and a main ribbon G isdisposed in front of the platen.
  • Work sheets H are led forwardly to the platen over a work guide I attached to the carriage, thence over a roller 5 journaled on the carriage, thence downwardly under a guide roller 6 journaled on the carriage below the platen, and thence upwardlypast the platen and have theirupper edge portions clam ed to a truck J whichis mounted on the col ating frame D for line spacing movements, the truck being line spaced by the lever E by a mechanism shown in said. co-pendin application.
  • A'spool supporting frame is disposed in rear of the main frame A and is attached to the carriage to move therewith, theframe K carrying rollers 7, 7 which ride along a rail 8 attached to the main frame A.
  • the spool frame K' comprises a substantially V-shaped bar 9 having its endjportions attached to the end plates of the carriage. Extending upwardly from the central portion or apex of the bar 9, are integral arms 10, 10 having a fulcrum bearing 11 formed therebetween.
  • each disc being provided with an eccentric circular opening 15 for receiving the shaft and with an angular opening 16 which merges with the opening 15 andinterlocks with the flat sides 13 of the shaft to retain the disc against rotation.
  • ribbon spools L Rotatably mounted on the shaft 12 and located between adjacent spacin discs are ribbon spools L, each comprising aliub 17 and carbon strips or ribbons M.
  • the carbon strips or ribbons M are led from the spools forwardly along the left side of the carriage, thence along and in front of the platen and in rear of the main ribbon G and in interleaved relation with the work sheets, and thence rcarwardly along the right hand side of the carriage to a rib bon feeding means 18 which includes co-opcrating feed rolls 20, 20.
  • the ribbon feeding means 18 is actuated from the collating frame D by connections shown in said copending application.
  • Means are provided for normally and collectively tensioning the spools against feeding rotation, and operat1ve means are provided for actuating the ribbon feeding means and increasing the action of the tensioning means to effect the locking of the spools against feeding rotation prior to the completion of the operation of the ribbon feeding means, whereby the last part of movement of the ribbon feeding means will render the ribbons taut and thereby prevent the worksheets from dragging the ribbons upwardly therewith during line Y spacing movements of said work sheets.
  • a stop 21 Threadably mounted on the outer end of the shaft 12 beyond the outermost spacing disc 14 is a stop 21, and slidable on the shaft between said disc and stop is a tension collar 22.
  • a coil spring 23 is disposed around the shaft between the stop 21 and collar 22.
  • a tension disc 24 Slidable on the inner end of the shaft 12- between the bar 9 of the spool frame K and the innermost spacing disc 14 is a tension disc 24 provided with a forwardly extending hub 25 and a forwardly extending guide pin 26 having a head 27 on its inner end, the pin having sliding engagement ina guide opening 28 formed in a bracket 29 fixed to and depending from the bar 9.
  • a vertical lever 30 is fulcrumed intermediate its ends on the fulcrum seat 11 of the bar 9 and the lower end of this lever is disposed between the bar 9 and the tension .disc 24, said lower end of the lever being formed with an opening 31 for receiving the inner end of the shaft 12.
  • the upper end of the lever 30 extends between the arms 10, 10 of the bar 9 and is engaged by a cam 32 fixed on a horizontal rock shaft 33 which is journaled in bearings 34, 34 located on the upper ends of the arms 10, 10 and in a bearing 35 formed on one end of the spool frame K.
  • a rock arm 36 In orderto rock the shaft 33 and thereby increase the tension on the spools so as to lock the latter against feeding rotation immediately prior to the completion of the ribbon feeding operation, I have provided said shaft 33 with a rock arm 36 to which I have pivotally connected one end of a link 37 the forward end of said link being pivotally connected to one arm of a bell crank lever 38 which is fulcrumed on the carriage and is operable upon swinging the carriage return lever E.
  • the ribbons will be held taut owing to the fact that the tension on the spools which had been increased remains in the same condition.
  • the amount of this increased tension applied to the spools may be varied by adjusting the therewith, ribbon feeding means mounted on the carriage, a horizontal spool shaft secured at one end to the spool frame, a ribbon spool including a hub rotatably mounted on said shaft, means located onopposite sides of the hub for normally and directly applying a slight tension thereto, and operable means for actuating the ribbon feeding means and concomitantly actuating said tension applying means to'further tension the spool against feeding rotation.
